the second largest economy in the united states. clearly wants to know who is going to be the next in charge. aren't they worried and ready to say something definitive? >> well, that's an interesting question. and one of the things i've been looking into as well is how are other politicians in china reacting during this period, this ten-day period where xi jinping has been awol. and it seems that they're going about their business. experts are saying if there was some giant crisis within the communist party right now and xi jinping is out of commission, then you might have seen them react differently. not leave beijing, for instance. which many of them have done. and one of the interesting theorys is look, the communist party in china is playing by very old rules. it's being secretive. it's not divulging information. and maybe this is benign. maybe nothing that dramatic has happened to xi jinping. but their reaction is making it worse. it's archaic and not in keeping with the times with twitter and other social media websites. perha
